The fact of the matter is that Yuki is not emotionless, she was designed to be “shy” but because her superiors do not fully understand humans, she is not fully capable of displaying emotions. But it is those few glimpses of her reacting to the world around her that make those moments and indeed every moment special just waiting to see her become closer to humanity. You claim she is unattractive but does every girl have to have ovacious curves and large breasts? No. Yuki has small features, she …

its because she hides her emotions when as supposed she shouldnt have had any,thus when at anytime she shows any little emotions , be it happy or sad , it is empified and leaves deep impressions. very unique setup. ps: i love nagato-chan rofl midori baloonn
